Title: 6V6 JCM800 channel switch
Post by: JGk on March 07, 2026, 09:20:39 am

Hi doing a JCM800 6V6 on an old chassis I have that has a single input and I would like to use a switch to go between the high and low outputs instead of re-drilling the chassis. I was wondering if anyone had build one and had a schematic or a layout available.

There’s a page in Sluckey’s Amp Scrapbook for that. You’ll still need a hole for a switch, though.

I answered this three days ago in the "6V6 JCM 800 build: re-tasking old build" topic.
